This invention relates to mechanism for the control of shuttle boxes of'weaving looms. According to theinvention a plate or disc .i iixedupon a rotatable shaft carries ltoothed 5 sectors disposed in a medial planeY common to their adjacent faces, andjeecting a half rotation of "four satellite pinions Vdisposed two and two in different pla-nes at each passage 'of ythe toothed sectors in engagement with, the respective pinions.- Two of these pinions togethercontrol, through a lever, the movementof the boxes to an'extent of four Y, boxes or less. The lthird pinion actuates by l means of a rod and a Abell crank lever, a l5 horizontal toothed rack causing as emi-rotationv of a pinion carried. by Va mainl lever whereby a crank, by which the lever opera-ted by the two first pinions isconnected to the main lever, is rotated and the main lever actuating the control rod of the boxes is caused to rise o r fall to an extent of four boxes. The vfourth pinion produces the same movement as thelthird pinion, but it actuates y a toothed raclrwhich .causes asemi-rotation of a pinion carried at the extremity of the main lever whereby afcranl,V to which the control rod yof the boxes is connected, is ro.- tated to eifect the riseor fall 'of the boxes to an extent of four boxes.

Thus any one of a-vnumberrof boxes,1 from oneto twelve may be positively moved into the'operative position,the third and fourth satellitej'pinions each causing the rise. or Y fall of the boxes to an extent of four boxes and the positioning of the intermediateboxes being always obtained as VhereinafterI described by ythe two .first satellite pinions referred to.v Y i c i.

Discs c, 0,1 and.l d, d1 are mountedcoaxially with the respective satellitepinions S1, ySi? and S3, S? and are `clutched thereto by means ofthe card'mechanism as hereinafter described., c The rod e1 pivoted tothe disc 01, isconnected by meansl of a;bellV crank lever'1 tof a rod m whichis articulated to a toothed rack 1. y The rack hlis ink engage?v Y ment with? apinion 1 rotatably Amounted upon the main control rod actuatinglever The control rod of the boxes represented In Y. the accompanying drawing the third box' is in the position of use and the batten ,is indicated at B, it being understood that vthe boxes are mounted in any "suitable manner permitting their vertical reciprocatio'n.`

'The rode pivoted to the disc c is vconnected by a bell cranlrlever f toa rod g whichV is articulated vto -atoothed rack L. The, rack k is in'engagement with the pinion z'. The two'rods n and nl pir'foted `to the 'discs elY and Z1 respectively varey articulated to a lever 0.V The pinions S1, S2 andS3, Sifco-rresponding to the discs.c,`,c1V ,and ail, d turn freely'uponzthe respectivev axes of the discs toy which latter'they are capable of being clutched by means each constituted of a pin p and a' spring g disposed in a concentric casing fr.

Bell crank levers t are connectedby cables u. to the card mechanism of the loom and on being actuated' by the card mechanism apply pressure upon thefpins e pi, which are thus pushed into one of two holes in the respective pinions which are thus fixed to the respective 'discs during the half rotation of the pinions by the toothed sectorsv b, b, and 51,6?.

'Ihe erankllevers are provided ind` pairs,

each pair being symmetrically disposed von a horizontal axis and at each side of the axis of the respective pinionl so that the pin p may be engaged in either of two positions.

Each disc 0, 01, d, Z1 is provided with a device comprising a spring pressed pin engaging with a plate or the like fixedly secured to the respective disc, the device acting as Ya brake and tending to cause relative movement of the disc and the respectivev4 pinion during their half rotation whereby the Vrespective pin p is subjected" to"- as light shearing action and is maintained within the hole inA the pinion until the half'rotationA is completed, whereupon the pin p isv withdrawn by its spring. Recesses may be provided in thev plate within whichga spring pressed pin may engage as shown'atA a' to maintain the disc in the position to which it has been rotated by the respective pinion. `'A springr is connected between afixed pointy and the main lever j for balancing the weighty of the boxes and the associated parts.

The opera-tion of the mechanism herein-V mounted upon a spindle pivoted on the lever j 'and carrying a crank' m1 to the outer end of which theendof the lever ois pivotally connected. Thus, the lever o beingsnspended lfrom the discs CZ and@1 by means ofthe rods n, nl so as to be capable of swinging longitudinally whereby, when the Vdiscs o l and c1 are held stationary, the pointat which the levero is pivotally connected tothe crank m1 is maintained substantially in the'sane horizontal plane on'V limited longitudinal movement ofthe lever o, the movement of the crank m1 by the operation of the disc di, through theV rod el, the' bell crank lever f1', rod m, rack h1, andpinion l causes the" axis of the crank and conseqn'ently the' lever to riseor to fall to an extent of fonr boxes".

When' theV card mechanism causes' the respective pinv p to engage with the pini'oi'i Sl thepinion inl its half rotation carries with it the disc c. The rod e. by means ofthe bell crank lever ',f, imparts a movement of translation to the lever g, and the toothed rack L causes a semi-rotation ofthe pinionz' which rotation isv communicated to 'af crank L tothe outer extremity ofwhichth'eno'ntrolv rod of 'the boxes is pivoted and canses the rise orfall of the' boxesl to' an extentbf fourjboxes; c v

When the card mechanism cases theengagement of the respect-ive pin p with the pinion S4 the pinion in its half rotation can ries with it the ldisc d, The 'corresponding rod n actuates the leverv o connected to the lever g by the crank m1 and causes the main lever j to rise or fall to an extent of two boxes.

When the card mechanism causes the engagement of the respective pin y) with the pinion S2,the pinion in its half rotation carries with it the disc 01. Thev corresponding rod nl actuates thek leverjyoconnectedtofthe main lever by means of the lcran'll:` m1 'and causes tlie'inain leverj to rise or fallto-an the Zero position, Vandthe first box is inV position.

In 'order to vbring" the second box into the operative position the disc 01 isl clutchedfto the pinion 'S2 asv hereinbefore describedwhile th'e'pinion turns through half a revolution whereby the lever 0 is inoved to an extent suiii'cient 'to raise the main lever to the extent of one box.

To bring the third `box intoy position,v the disc d' isactuate'dtolli'ft the lever 0 to canse ariseof two boxes and the disc c1 is re turned to the Zeropo`s'itio1i;

`Tob'rii'igthe 'foiifrth l`box into position, the disc' el, is' maintained 'in the positionl corre# sponding tothe third box Vand 'theld'sc c1 is actnatedv to move'th-e lever' 0* and to raise the main lever to the extent of onebox;

To bring the boxrintio position,V the disc c 'or Z1Y is actuated' as hereinbefore de- L'scriloedto cause the rise of'foiir'boxes and the discs (Zand cl'aremove'd' to the positions correspondingto the first box, thatis toA their `fzjer'o positions.

For the sixtlr, seventh 4andleighth boxes the disc 0 ordl remains stationary and the discs Z and 01` are moved into vthe positions corresponding to the second, third, and fourth' boxes. f Y

To'bring the ninth box into position both the discs o and (Z1r are actuated tio cause tle total rise of eight boxes and the discs d and'c1 are moved into Vthe positionsvcorresponding to the lirst box, that isA into their 'zero positions. lVhile to bring the tenth,
